(Him: Be sure to check for inuential observations and outliers.) 9. 18 ( Data file : cloud) The data summarize the results of the first Florida Area Cumulus Experiment , or FACE- 1 , designed to study the effective - ness of cloud seeding to increase rainfall in a target area ( Woodley et al .. 1977). A fixed target area of approximately 3000 square miles was estab - lished to the north and east of Coral Gables , Florida . During the summer of 1975, each day was judged on its suitability for seeding . The decision to use a particular day in the experiment was based primarily on a suit - ability criterion 'S depending on a mathematical model for rainfall . Days with S _ 1.5 were chosen as experimental days ; there were 24 days chosen in 1975 . On each day , the decision to seed was made by flipping a coin ; as it turned out , 12 days were seeded , 12 unseeded . On seeded days , silver iodide was injected into the clouds from small aircraft . The predictors and the response are defined in Table 9.5 . The Goal of the analysis is to decide if there is evidence that cloud seeding is effective in increasing rainfall . Begin your analysis by drawing appropriate graphs . Obtain appropriate transformations of predictors . Fit
